HZ系列滑动闸门用于建材、冶金、矿山、电力、化工、玻璃、轻工、粮食等行业的库顶、库底及进出口等。是控制流量变化较大，启动频繁，切断迅速的理想设备。
This valve is widely used at the top and bottom of store house and carrying port in metallurgical, mining, building material, food, chemical industries etc. It is the ideal equipment to control a great changing flow, to open and close frequently and to stop quickly.
结构特点：
Structure characteristic:
体腔内设灰斗卸料，避免物料冲击体腔，延长了使用寿命，闸板运动由滑轮导向，减小了运动阻力，操作更加灵活、切断快速，特别适用于各类微带粘度的固体、粉料及小于Φ10mm的颗粒料，晶粒料的输送及流量调节，安装不受角度限制， 能随时调节开度。该阀门有手轮和链轮两种操作形式，I型为手轮，II为链轮。单向和双向两种结构形式，HZD为单向，HZS为双向。
There is dust- ladle in body, which prevents body from impacting of material and prolongs the service life. The slide plate is guided by pulley, which reduces motive resistance. The valve is handy to operate, light in weight, non-obstructive and quick to stop. It is suitable to be used to carry all kinds of solid material of little viscosity, particle and crystal particle whose diameter is below 10mm and to adjust the flow. It can be installed at any angle. The position of its gate can be regulated at any time. This valve has two type of operation. One is manual wheel operation; the other is chain wheel operation. TypeⅠ means manual wheel. Type Ⅱ means chain wheel. The valve has two type of construction HZD is signal direction and HZS is double direction.

工作原理：
Working principle
主要由框架、闸板、丝杆、螺母等零件构成，人工转动手轮使带动丝杆螺母和闸板作水平方向往复运动，达到启闭目的。闸板的运动像刀铡一样能切断滞留在灰斗上的物料，达到密封状态。
It is made up of frame, slide plate, screw bolt, nut etc. rotate the hand wheel to realize the horizontal reciprocating motion of nut and slide plate and the open-close of gate. The movement of slide plate is like that of hay cutter, which can cut off the material lagging on the dust-ladle and make the valve in sealed state.

使用说明：
Usage explanation:
l 本阀可水平安装或垂直安装，安装时两法兰连接中间必须加密封垫片，然后锁紧螺栓。
l 操作时手轮顺时针旋转为阀关，反之为开，不得在手轮上再增加辅助杠杆。
l 若长期存放应使设备处于关闭状态，各传动部位应加润滑油，不允许露天存放或堆置。
l It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt.
l You cannot add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve, otherwise it means opening.
l The device should be in the shutdown if the valve-board is placed longer. Driving parts should add lubricated oil. Placing in the open and piling up is not permitted.
